And therein lies the rub. Unreal 5 is massive and complex, and there comes a point where it takes longer to understand how to layer on your own customizations than just to start from scratch. Especially for indie developers.

I wanted to make a little editor utility (the UE editor is built in UE) that changed the way viewport selection was handled. I think I got to 5 layers of abstraction before I gave up. 5 layers, for a left-click object select.
